The Cressi-sub MC7 Diaphragm regulator is a technically
advanced regulator made with the highest quality materials and
workmanship. It is designed to offer years of top performance
and reliability.
1.2 - Antifreeze Kit
WARNING: Proper training is required in order to safely
dive in cold (less than 10°C) water. Before diving under these
conditions, Cressi-sub recommends that you attend a spe-
cialty, cold water course conducted by qualified instructors.
The regulator should not be placed in water prior to use and
then exposed to the air (which is likely to be several degrees
below zero). Do not operate the purge button, especially
when the Venturi knob (Dive / Pre Dive Switch) is in the "dive"
position. If possible, keep the regulator in a warm place before
use.
The Antifreeze Kit is used to seal off or waterproof the MC7
Balanced diaphragm first stage, thus, preventing water from
entering. Additionally, it prevents water from coming in contact
with the diaphragm and the main spring, and a water-tight air
chamber is created within the first stage, which acts as a thermal
barrier. In this way, problems related to contact with cold water
are avoided, especially at temperatures less than 10°C.
Sold separately from the regulator, the Antifreeze Kit is easy to
install. It features a metal (No 20K) cover with a silicone
diaphragm inside. When sensing any ambient pressure change,
the diaphragm flexes inward and transmits the movement over
to the underlying disk. The latter unit, being in contact with the
main diaphragm, acts as a transmission element and transmits
pressure change information onto the diaphragm. The main
diaphragm protects and seals the inner system mechanism, and
transmits the information on water pressure changes to the high
pressure seat (8K).
WARNING: After having mounted the antifreeze kit, the
MC7 Balanced Diaphragm 1st Stage must be reset.
WARNING: The intermediate pressure should only be
adjusted by Cressi-sub authorized centers. Changing pre-set
values can affect the proper function of the regulator.

between 1
stage and air supply. It is constructed of a chrome-
plated brass body. All internal components are made of stainless
steel and chrome-plated brass, with stainless steel springs and
NBR O-rings.
Many technical and aesthetic innovations make this first stage
different from the previous models and place it at the top of our
product line, while maintaining its features of high reliability and
durable construction.
